Öncelikle verilen A ve B ifadelerinin değerlerini hesaplayalım:
A = (sin x . sec x)² - (tan x . cosec x)²
A = (sin x / cos x)² - (sin x / cos x)²
A = sin² x / cos² x - sin² x / cos² x
A = 0
B = 2 - 2cos² x + cos⁴ x - sin⁴ x
B = 2 - 2cos² x + (cos² x)² - (sin² x)²
B = (cos² x)² - 2cos² x + 2
Şimdi 2A + 3B'yi hesaplayalım:
2A + 3B = 2(0) + 3[(cos² x)² - 2cos² x + 2]
2A + 3B = 3cos⁴ x - 6cos² x + 6
Bu şekilde 2A + 3B ifadesinin ayrıntılı hesaplanması tamamlanmış oldu.

What are the polar coordinates of the point A shown below?
A point plotted on a polar coordinate plane.
Select the correct answer below:
(−2,3π4)
(1,−π4)
(1,−7π4)
(2,−π4)
(−2,π4)
(1,3π4)
Answer:(1,−7π/4)
Step-by-step explanation:
Note that the point is on the circle whose radius is labeled 1, so r=1 or −1. Of the choices available, only an angle of −7π4, drawn from the positive x axis plots at the point A. So θ=−7π4, and r must be positive, as the angle is measured from the positive x axis. Thus, the polar coordinates are (1,−7π4).

Since the graph was obtained by transforming the graph of the square root function, an equation for the function the graph represent is: [tex]g(x) = -\sqrt{9(x - 1)} + 2[/tex]
What is a square root function?In Mathematics and Geometry, a square root function is a type of function that typically has this form f(x) = √x, which basically represent the parent square root function i.e f(x) = √x.
In Mathematics and Geometry, a horizontal translation to the right is modeled by this mathematical equation g(x) = f(x - N) while a vertical translation to the positive y-direction (upward) is modeled by this mathematical equation g(x) = f(x) + N.
Where:
N represents an integer.g(x) and f(x) represent functions.In this context, the required square root function can be obtained by applying a set of transformations to the parent square root function as follows;
f(x) = √x
g(x) = -√9(x - 1) + 2

What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (- 4, 0) and (0, 2).
Now,
Since, The equation of line passes through the points (- 4, 0) and (0, 2).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (2 - 0) / (0 + 4)
m = 2 / 4
m = 1/2
Thus, The equation of line with slope 1/2 is,
⇒ y - 0 = 1/2 (x + 4)
⇒ y = 1/2x + 2
Therefore, The equation of line is,

Differentiate y=3xcosx+sinx
Answer:
Step-by-step explanation:
To differentiate y = 3x cos(x) + sin(x), we can use the product rule and the chain rule.
Let's start by differentiating the first term, 3x cos(x), using the product rule:
d/dx (3x cos(x)) = 3 cos(x) - 3x sin(x)
Next, we can differentiate the second term, sin(x), using the chain rule:
d/dx (sin(x)) = cos(x)
Putting it all together, we get:
dy/dx = 3 cos(x) - 3x sin(x) + cos(x)
Simplifying the expression, we get:
dy/dx = (4cos(x)) - (3xsin(x))
Therefore, the derivative of y = 3x cos(x) + sin(x) is dy/dx = 4cos(x) - 3xsin(x).
(HURRY) Based on the data in the graph, to the nearest degree, how much greater is the mean temperature of the orange juice than the mean temperature of the water?
The mean temperature of orange juice is 5 degrees greater than the mean temperature of water.
The mean is a measure of central tendency that represents the average value of a dataset. It is calculated by adding up all the values in the dataset and then dividing by the total number of values.
According to the graph, the different temperatures of water and orange juice on different time can be taken into consideration.
Sum of Temperature of Water at different time
= 55 + 62 + 69 + 71 + 79 + 75
= 441 degrees
Mean Temperature of Water
= 441/6
= 68.5 degrees
Sum of Temperature of Orange juice at different time
= 59 + 65 + 72 + 79 + 85 + 81
= 441 degrees
Mean Temperature of Orang juice
= 441/6
= 73.5 degrees
Difference = 73.5 - 68.5 = 5 degrees
Hence, the mean temperature of orange juice is 5 degrees greater than the mean temperature of water.

31. There are two gears that are connected to each other. One gear has 20 teeth and the other gear has 10 teeth. If the bigger gear turns around 5 times, how many times will the smaller gear turn?
10 times will the smaller gear turn.
What is the ratio?
The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Since the smaller gear has 10 teeth and the bigger gear 20, the smaller gear will turn twice for every rotation of the larger gear (20/10=2).
Therefore, if the larger gear rotates five times, the smaller gear will rotate two times five times, or ten times. The smaller gear will thus rotate 10 times.
So, if the bigger gear turns around 5 times, the smaller gear will turn around 5 x 2 = 10 times.
Therefore, the smaller gear will turn 10 times.

Let x be the number of 16 oz jars of peanut butter collected, and y be the number of 28 oz jars of peanut butter collected.
The system of equations that represents the constraints in this situation is:
x + y = 82 (total number of jars collected)
16x + 28y = 1876 (total amount of peanut butter collected in ounces)
b. To solve for the number of 16 oz jars and 28 oz jars of peanut butter donated to the food bank
we need to solve the system of equations from part (a). One way to do this is to use elimination:
Multiplying the first equation by 16, we get:

To prepare a direct materials purchases budget for Solid Grip Company,
The amount of rubber and steel belts needed for the production of 66,000 passenger car tires and 20,000 truck tires.
The desired ending inventories and estimated beginning inventories for each material.
First, let us calculate the amount of rubber and steel belts required for the production of passenger car and truck tires.
Passenger car tires,
Rubber,
66,000 tires x 33 lb. per unit = 2,178,000 lb.
Steel belts,
66,000 tires x 5 lb. per unit = 330,000 lb.
Truck tires,
Rubber,
20,000 tires x 77 lb. per unit = 1,540,000 lb.
Steel belts,
20,000 tires x 13 lb. per unit = 260,000 lb.
Next, let us calculate the total amount of rubber and steel belts needed for production.
Rubber,
2,178,000 lb. + 1,540,000 lb. = 3,718,000 lb.
Steel belts,
330,000 lb. + 260,000 lb. = 590,000 lb.
To calculate the total amount of rubber and steel belts required for purchase,
Add the desired ending inventories and subtract the estimated beginning inventories,
Rubber,
3,718,000 lb. + 62,000 lb. - 73,000 lb. = 3,707,000 lb.
Steel belts,
590,000 lb. + 13,000 lb. - 11,000 lb. = 592,000 lb.
Finally, calculate the total cost of rubber and steel belt purchases.
Rubber,
3,707,000 lb. x $2.90 per pound = $10,749,300
Steel belts,
592,000 lb. x $3.80 per pound = $2,249,600

Gordon runs for 28 minutes on Monday and 43 minutes on Wednesday. Write and solve an equation to find how many more minutes Gordon ran on Wednesday
Compared to Monday, Gordon ran for an additional 15 minutes on Wednesday.
Let x be the number of additional minutes Gordon ran on Wednesday compared to Monday. Then, we can write an equation based on the given information:
43 minutes (Wednesday) = 28 minutes (Monday) + x minutes (additional time on Wednesday)
To solve for x, we can isolate it on one side of the equation:
43 minutes - 28 minutes = x minutes

Lia prepared 35 kilograms of dough after working 7 hours. How much dough did Lia prepare if she worked for 9 hours?
Just write the number for your answer please.
Answer:
We can use the proportion method to solve this problem.
Let's define the rate of dough preparation as the amount of dough Lia can prepare per hour. We can write:
rate = amount of dough / time
We are given that Lia prepared 35 kg of dough in 7 hours. We can use this information to find her rate of dough preparation:
rate = 35 kg / 7 hours = 5 kg/hour
Now we can use this rate to find how much dough Lia will prepare if she works for 9 hours:
amount of dough = rate x time
amount of dough = 5 kg/hour x 9 hours = 45 kg
Therefore, if Lia works for 9 hours, she will prepare 45 kilograms of dough.
